The bail strap or band 7 is 55 proveniente in .Iar- Covers and Fastenings drilled at its diametrically opposite sides to Therefor, of which the following is a specifireceive the bottom bends or hinged endsS of cation. 1 the bail 9 to form a pivotal or hinged connec- My invention relates to certain new and tion thereat.

The inner surface of the cover lOis the said improvements are particularly applidished 1o an extent to clear the end ofthe lip cable to that class of jars employed in can- 4 when placed over the mouth of the jar, and ning fruit, and will be hereinafter more fully its'annular bearing edgeor base-1l bears or :5 described, and particularly pointed out in the rests on the gasket 5, and the top side of said 65 claims. cover is formed to present a gradually-as- The object of my invention is to provide a cending, spherical, or cam surface 12, comcover and a fastening means therefor, which mencing at its base or bottom bearing edge latter means may be adj usted to loosely reand terminating atits central portion orapex,

zo vtain the cover or cap of the jar on the latter, at which point a round recess 13 is formed 7o and thereby permitlhe hot air, vapor, or and is provided for the purpose of forming a gases generated or escaping from the hot maretaining or locking means to retain the lockterial with which the jar is charged to escape ing-ball 14 and lock the bail 9 in position to freely, and when the contents of the said jar retain the cap 10 rmly in position upon its have cooled sufficiently said fastening means gasket 5 to hermetically seal thejar. Inter- 75 may be caused to more rigidly and securely mediate of the bottom bearing edge or base press the cover upon the mouth of the jar to of the cover 10 and the top recess 13 is formed hermetically seal the same. I attain these the annular recess 15, which is concentric objects by means of the cap and fastening with the center of theV cap and is bound by the 3o means illustrated in the accompanying drawannular bead or shoulder 16, the object and 8o ings, in which similar numerals of reference purpose of which I will hereinafter describe. designate like parts throughout the several The bail 9 is of a length suflciently great views. that When moved into the position B, shown Figure 1 is a sectional View of a fruit-jar, in dotted lines, (see Fig. 2,) the locking-ball taken through the plane designated `by the 14 will drop into the annular recess 15 to mod- 85 lines A A (see Figs. 2 and 3) and illustrating erately bind thereon, and thereby loosely remy invention applied thereto. Fig. Zisasimitain said cap or cover 10 in position on the lar sectional view taken through the plane gasket 5 to slightly clamp the latter. When designated by the lines B B. (See Figs. 1 and it is required to lock the cap l0 in position to 4o 3.) Fig. 3 is a detail perspective view of the tightly clamp the gasket 5 to hermetically 9o jar, and Fig. et isa detail perspective view of seal the jar l, the bail 9 is moved over the the locking bail or yoke by which the cap or center of said cover 10 till the locking-ball 14: cover of the jar is secured thereon. enters th'e recess 13 to lock said bail 9 in its The body l of the jar may be of any suitcentral position over the central raised porable size and form and is provided with the tion of said cover, and thus tightlypress the 95 reduced or neck portion 2, the collar or enbottom bearing edge or base 1l against the larged neck portion 3, and the annular or lip gasket 5 to tightly clamp the same on the portion 4. Agasket 5, of rubber or other suitshoulder 6 of the collar 3, andthus hermeticable pliable packing material, surrounds the -ally seal the jar.

5o neck 4t and rests on the top or shoulder 6 of The cap or cover being first removed from roo the jar, the preserved fruit or other composition of matter to be preserved for future use when fully cooked or otherwise prepared is poured into the jar 1 to almost completely fill the same. The gasket 5 is now placed in position to encircle the lip 4 and rest on the bearing-shoulder 6 of the collar 3. The cap 10 is now placed over the lip 4:, with its bottom bearing edge or base 11 resting upon the gasket 5, and the bail 9 is moved from its position A to B, as shown in dotted lines, (see Fig. 2,) to lock the ball 14 in the groove 15 to retain the cap 10 loosely but seeurelyin position over the mouth of said jar to permit the vapor, air, or gases generated or exuding from the prepared material to be freely expelled, after which and when the said material has cooled sufciently the bail 9 is moved into the position C-that is, centrally over the top of the cap lO-till the locking-ball 14 thereof drops into or engages the central recess 13 of said cap to secu rely retain the latter in position over the mouth of the jar and hermetically seal the same. It will be observed, however, that the varying degree ot pressure is effected by positioning the bail either upon the annular shoulder 1G or in the recess or depression 13, and inasmuch as the shoulder 1G is in the form of a ring and extends entirely around the cover it will be seen that no care is necessary in positioning the cover upon the jar, but in any position in which it may be placed the ball may be engaged therewith eifectually. Itis also obvious that irrespective of the position of the cover the ball will always engage the recess or depression 13.

Having thus fully described this my invention, whatI claim as new and useful, and desire to cover byLetfers Patent of the United l States therefor, is-

1. In ajar-cover and fastening for the saine, the combination with the body of the jar, and a cover provided with a gradually-ascending surface having at its apex a depression or recess, said cover being also provided at a poi nt intermediate its lower edge and said depression or recess with an annular bead or shoul der, of a bail pivotally connected to the body of thejarand provided with an enlarged portion adapted to be seated upon said annular shoulder or be received by said recess or depression at the apex of the cover, according to the degree of pressure which it is desired to impart to the cover.

2. In a jar-cover and fastening for the same, the combination with the body of the jar, and a cover provided with a gradually-ascending surface having at its apex a depression or recess, said cover being also provided at a point intermediate its lower edge and said depression or recess with an annular bead or shoulder, of a bail pivotally connected to the body of the jar and provided with a ball adapted to be seated upon said annular shoulder or be received by said recess or depression at the apex of the cover, according to the degree of pressure which it is desired to impart to the cover.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
